Lever type Limit Switch
Introduction :
Lever Limit Switch is used for heavy duty E.O.T. Cranes, Wagon shunting devices etc., to prevent over travelling or
over traversing on power and control circuit up to 500 volts A.C. 50 Hz and 10amps and 40 amps current rating.
Function :
The lever Limit switch operates when its lever reaches its pre-determined position and the lever is moved over a
projecting member fixed on the Girder.
The Limit Switch contacts are automatically reset when the lever returns to zero position due to spring action.
Technical Data:
Body Material : Powder Coated Aluminum die cast
Degree of Protection : IP-55
Mounting Position : Floor
Cable Entries : 2, 3/4" Conduit
No. of Contact : 2/3/4
Contact : Double break silver cadmium
Wire Connection : Screw terminal
Rated Voltage Insulation : 500 V.A.C.
Thermal Test Current :10/40 Amps.
Operation : 720/hour

3. ROTARY GEAR LIMIT SWITCH
Rotary geared type Limit Switch is basically consists of heavy duty worm gear drive. The worm gear unit is built in
a cast housing fitted on main body of Limit Switch. The cam shaft which extends from behind the gear in to
housing, accommodates the cams adjustable actuators which are fitted on the cams. These actuators strikes the
contact finger of respective contacts
Function :
Limit Switch is to stop the mechanism of drive at the extreme clock wise / anti clock wise position. These Rotary
Limit Switches are particularly suited for use on reversing drives such as Electric Hoists, Winches, Over Head
Cranes, Traversers etc.
Application:
Rotary geared type limit switches are suitable for use reversing drives such as hoists, winches,
rolling mills and various other mechanisms used such used in steel plants such as coke oven,
feeding machinery etc.
Technical Data:
Body Material : Aluminum die cast
Degree of Protection : IP-55
Gear Ratios : 1:48, 1:60
Drive : Worm Drive
Cable Entries : 3/4" Conduit
Contact Material : Double break silver cadmium
Rated Voltage Insulation : 500 V.A.C.
Thermal Test Current : 10/40 Amps.
NO. of Contacts : 6 maximum
Cam setting : adjustable
Contacts : Normally open / Normally close

5. WARM DRIVE LIMIT SWITCH
Application:
The new range of limit switches has been designed and manufactured according to safety
standard are suitable for use on reversing drives such as hoists, cranes, winches and rolling mills
etc.
Design:
The driving motion is transmitted by worm gear. All gears and hubs are made of low wear
thermoplastic. The rotational movements are transmitted to switches by adjustable cams.
Driving cams:
Each lever has a single micrometric resister screw.This screw exclusively works on its own
combined lever, excluding any mechanical contact with any other next to it. The regulation is
easily made by use of screwdriver on a register screw. The special friction system assures a
rapid and precise adjustment.
Technical Data:
Body Material : Black Nylon
Cover Material Yellow : Impact proof thermoplastic
Protection Degree : IP-55
Mounting Position : Any
Gear Ratios :1:12.5, 1:25, 1:50, 1:100, 1:200 & 1:400
Drive : Worm Drive

Mechanical Data:
Ratios Effective Rotations Useful Rotations
1:12.5 12 11.6
1:25 24.5 23.2
1:50 49 46.5
1:100 98 93
1:200 196 185
1:400 392 372

7. WEIGHT OPERATED LIMIT SWITCHES
Introduction :
Weight operated Limit Switches are used on Control / Power circuit of reversing drives so as to limit their rotation /
movement within a predetermined position.
Operation :
When the Snatch Block of the Crane reaches its top position the Snatch Block pushes a Plate which is hanging from
one end of the Lever of the Limit Switch. Due to the weight placed on the other end of the lever this lever is pushed
up.
When the lever is pushed up the shaft to which this lever is connected rotates there by rotating the cams which
eventually open the contacts and disconnect the motor
The Limit Switch contacts are automatically reset when the lever returns to zero position due to Gravitational force.
Technical Data:
Body Material : Powder Coated Aluminum die cast
Degree of Protection : IP-55
Mounting Position : Floor
Cable Entries : 2, 3/4" Conduit
No. of Contact : 2/3/4
Contact : Double break silver cadmium
Wire Connection : Screw terminal
Rated Voltage Insulation : 500 V.A.C.
